CHALET C7, by architectsNicolás del Río and Max Nunez, is located in the Andes and Portillo precisely in the region of Valparaiso Chile, a 2990 meters above the sea level. The house is perfectly hidden in the ground so as to interfere as little as possible with the breathtaking view of the lake; only a small entrance is visible from the top and then lead through a narrow passage to the shelter below.

The interior is organized on two levels. The first plane is defined by a stone wall that protects from snow in winter. Here are the bedrooms and private areas of the house. Al secondo piano vi è invece una zona completamente aperta che permette di godere appieno del paesaggio e della spettacolare aurora boreale.
